Application filed July. '22,

My invention relates to boats and in particular to h .l on t ct onz 9 he hulls thereof. I V, U

. It is the object of my invention toprovide asimply-constructed boat, capable of being assembled in sections and produced in quanf It is the object of my invention toproviole a system of reinforcingthe construction in such a way as to provide, the max mum strength with the minimum weight, together with simplicity'of construct-ion, fac litating assembly and manufacture, I

Referring t'othe drawings:

Figure l is a side-elevation of a boat constructed according to "my invention;

Figure 2 is a section on the line 22 of Figure 1 looking in the direction of' the arrows' Figure 3 is a-section on the line 3- 3 of Figure 2 looking in the direction ofthe ar rows.

Referring to the drawings in detail, it will be noted that the boat consists of a plurality of transversely continuous overlap ping sections of metal, designated 1, 2, 3, 4 and 5 reading from the bow to the stern.

The rear edge 6 of any given section overlaps the forward rib edge 7 of any succeeding section and may be countersunk thereln so that the outer surfacesof the two sections will be flush andthe overlapping portion of the succeeding section will be turned up at right angles to its major axis, as at. 8, to form a transverse rib.

Thus, I provide, integralwith the body sections themselves," ribs located at the points of greatest weakness and by countersinking the preceding section so that theexterior surfaces are flush, I provide a boat ance. I

If desired, supplementary angular rib members 9 can be provided to supplement the reinforcing of the integral ribs of the sections. Thus, my invention is characterized by a succession of transversely continuous. overlapping sections presenting a flush exterior surface and a plurality of integrally formed ribs adj acentthe joints of the sections.

' In addition to the foregoing, my invention is characterized by having an exterior continuous bow stem and keel member semi circular in section, designated 10, having diverging flanges 11 adapted to be attached 1e2 s ria 'no, 124,208.

tofthefbody sections, thereby forming a 1ongit udinal; reinforcing rib and'keel member combined as welfa'san integralstem for the bow. I "In order to' provide a well-defined chine line, I provide exterior angular c'hine' plates preferably extending continuously fore and aft, 'designa't'edflil. These plates are. likewise attached to the js'ections I-an'd serve L to hold the sections to one another,'just as 'a' keelmember so serves.

my boat', I have provided therefore three, groups of elementsieasily assembled and all mutually supporting tolprovide a,

very rigid structure, such as overlapping sections' with integrally formed ribs, the keel member and the chine members.

I also provide members extending fore and aft whichservethe same reinforcing and connecting purposes and also function as the gunwale, designated 13.

This member is provided with a flan e 14' and an overlapping cap member 15 to overlapthe ends of the ribs to provide aneat appearance for the boat and to prevent anyone being'injured on the sharp edges of the ribs Where they project upwardly. 7

It will be understood that I desire tocomprehend Withinmy invention such modifica-' tions as maybe necessary to adapt it to varying conditions and uses.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is e 1. In a boat, a hull formed of a'plurality of successive sections having their transverse edges overlapping one another said sections being formed ofa continuous piece of mate rial from one side of the boat to the other so as to form a flush exterior surface.

2. In a boat, a hull formed of a plurality of successive sections having their transverse edges overlapping one another, one section being recessed to receive theedge of the adjacent section to present a flush exterior surface said sect-ions being continuous from'one side of the boat to the other.

'3. In a boat, a hull composed of a succession of transversely continuous sections having their edges overlapping each one of said sections having an integrally-formed rib on i the edge adjacent to the next adjacent section the overlapping edgebeing turned inwardly in a vertical plane to form the reinforcing rib.

4. In a boat, a hull formed of a succession of transversely continuous sectionshaving overlapping edges, and means extending fore and aft of the boat body overlapping said sections to reinforce and connectthem together, said means consisting of a keel member, and chine members said keel and chine members being located completely exterior of the exterior portions of the sections Without interrupting the continuity of the sections.

5. In a boat, a hull formed of a succes sion of'transversely continuous sections having overlapping edges, and means extending fore and aft of the boat body overlapping said sections to reinforce and connect them together, said means consisting of a keel member, chine members and a gunwale member said members being so arranged as not to interrupt the transverse continuity of the sections. v

6. In a boat, a body consisting of a plurality of successive overlapping sections, each one of said sections having an integrally formed rib adjacent its line of connection with theadjacent sectionand a plurality of overlapping longitudinally extending, con- 7 nec'ting and reinforcing membersadapted to 7. In a boat, a body consisting of aplurality of transversely continuous successive overlapping sections, the edges of one section' being countersunli in theadjacent section to present a flush exterior andeach one of said sections having one of its edges formed into a reinforcing rib, a continuous stem and keel piece disposed externailly of said sections to connect them to one another and'chine pieces located on the exterior of said body extending fore and aft connecting said sections'to one another.

In testimony whereof, I aflix my signature.
